研究沉管隧道侧向集中排烟模式下排烟口的开启策略. 采用数值模拟和物理试验2种手段,在保证流量均匀的前提下,通过调整各排烟口的有效过风面积,得出沉管隧道侧向排烟时不同排烟口开启组合工况下各排烟口的合理开启角度,为沉管隧道火灾工况下通风排烟策略的制定提供基础性数据.
研究沉管隧道側嚮集中排煙模式下排煙口的開啟策略. 採用數值模擬和物理試驗2種手段,在保證流量均勻的前提下,通過調整各排煙口的有效過風麵積,得齣沉管隧道側嚮排煙時不同排煙口開啟組閤工況下各排煙口的閤理開啟角度,為沉管隧道火災工況下通風排煙策略的製定提供基礎性數據.

This paper studies the strategies for opening smoke vents in centralized smoke extraction mode on the side of immersed tube tunnels. The paper obtains reasonable opening angles of all smoke vents under the operating conditions of opening combination of different smoke vents during side smoke extraction of immersed tube tunnels by means of 2 means, i. e. numerical simulation and physical test on the premise of guaranteeing uniform flow and by adjusting effective wind pass area of all smoke vents to provide fundamental data for formulation of ventilating and extracting strategies of immersed tube tunnels under fire conditions.
